Scientists in Action: End of the Dinosaurs, Rise of Mammals

Program Description

Sixty-six million years ago, a meteorite larger than Mount Everest slammed into Earth, catalyzing a mass extinction that spelled the end for 75 percent of life on Earth, including the dinosaurs. This cataclysmic event has long fascinated paleontologists: How do we know that this impact occurred, millions of years before humans evolved? What evidence emerges from hillsides, craters, and fossils? And, of course, what happened next? Join paleontologists from the Denver Museum of Nature & Science for a live look at the dramatic end of Tyrannosaurus and Triceratops, and the dawn of the age of mammals.
